Design a Custom BoardAbout This Component
Microprocessor supervisory circuit with precision 3.3V supply voltage monitor and power-on reset generator. Provides 200ms fixed delay reset timing without external capacitors, integrated watchdog timer, and power-fail warning output. Designed for DSP, microcontroller, and processor-based systems with ≤50µA supply current.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
